Using xsi:nil in XML

Question

I am generating an XML file from a VB.NET app. The document was generating fine before I tried to add nillable elements. I am now testing putting in just one nil element as:

<blah xsi:nil="true"></blah>

Once this element is in place and I try to view the XML file in IE it is unable to display. I am receiving:

>  The XML page cannot be displayed 
> Cannot view XML input using XSL style
> sheet. Please correct the error and
> then click the Refresh button, or try
> again later. 
> 
> --------------------------------------------------------------------------------
> 
> The operation completed successfully.
> Error processing resource

If I remove this one element it displays fine again. What am I missing here?

Answer 1

Do you have xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" to declare the xsi namespace set on the root element of your XML?
